The following command was used to clang-format these files:
clang-format-18 -i $(find . \
-not \( -path "./\.*" -prune \) \
-not \( -path "./Base/*" -prune \) \
-not \( -path "./Build/*" -prune \) \
-not \( -path "./Toolchain/*" -prune \) \
-not \( -path "./Ports/*" -prune \) \
-type f -name "*.cpp" -o -name "*.mm" -o -name "*.h")
There are a couple of weird cases where clang-format now thinks that a
pointer access in an initializer list, e.g. `m_member(ptr->foo)`, is a
lambda return statement, and it puts spaces around the `->`.
Changes the signature of queue_global_task() from AK:Function to
JS::HeapFunction to be more clear to the user of the function that this
is what it uses internally.
This piggybacks on the same fragment serialization code that innerHTML
uses, but instead of constructing an imaginary parent element like the
spec asks us to, we just add a separate serialization mode that includes
the context element in the serialized markup.
This makes the image carousel on https://utah.edu/ show up :^)
This fixes the relevant warnings when running LibJSGCVerifier. Note that
the analysis is only performed over LibJS-adjacent code, but could be
performed over the entire codebase. That will have to wait for a future
commit.
No need to force an allocation. This makes a future patch a bit simpler,
where we will have the encoding as a String. With this patch, we won't
have to convert it to a ByteString.
The spec for each of these state:
-> EOF:
This is an eof-in-comment parse error. Emit the current comment
token. Emit an end-of-file token.
We were neglecting to emit the current comment token before emitting an
EOF token. Note the existing EMIT_CURRENT_TOKEN macro was unused.
This URL library ends up being a relatively fundamental base library of
the system, as LibCore depends on LibURL.
This change has two main benefits:
* Moving AK back more towards being an agnostic library that can
be used between the kernel and userspace. URL has never really fit
that description - and is not used in the kernel.
* URL _should_ depend on LibUnicode, as it needs punnycode support.
However, it's not really possible to do this inside of AK as it can't
depend on any external library. This change brings us a little closer
to being able to do that, but unfortunately we aren't there quite
yet, as the code generators depend on LibCore.
Normally, assigning to e.g document.body.onload will forward to
window.onload. However, in a detached DOM tree, there is no associated
window, so we have nowhere to forward to, making this a no-op.
The bulk of this change is making Document::window() return a nullable
pointer, as documents created by DOMParser or DOMImplementation do not
have an associated window object, and so must be able to return null
from here.
If a call to `document.write` inserts an incomplete HTML tag, e.g.:
document.write("<p");
we would previously continue parsing the document until we reached a
closing angle bracket. However, the spec states we should stop once we
reach the new insertion point.
HTML fragments are parsed with a temporary HTML document that never has
its flag set to say that it is ready to have scripts executed. For these
fragments, in the HTMLParser, these scripts are prepared, but
execute_script is never called on them.
This results in the HTMLParser waiting forever on the document to be
ready to have scripts executed.
To fix this, only wait for the document to be ready if we are definitely
going to execute a script.
This fixes a hang processing the HTML in the attached test, as seen on:
https://github.com/SerenityOS/serenityFixes: #22735
The fix here was to stop using StringBuilder::append(char) when told to
append a code point, and switch to StringBuilder::append_code_point(u32)
There's probably a bunch more issues like this, and we should stop using
append(char) in general since it allows building of garbage strings.
This is a little awkward: The spec requires when loading media documents
or ones that don't have a DOM, that we "act as if the user agent had
stopped parsing document" which means following this algorithm. Only a
few steps require an HTMLParser, but those that do, involve reaching
into its internals. The simplest solution I could think of (other than
duplicating this fairly hefty function) is making it static and taking
a Document and optional HTMLParser as parameters.
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:
```
Optional<I> opt;
if constexpr (IsSigned<I>)
opt = view.to_int<I>();
else
opt = view.to_uint<I>();
```
For us.
The main goal here however is to have a single generic number conversion
API between all of the String classes.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
As far as I can tell all of these steps are just equivalent to using the
qualified name. Add some tests which cover some of these cases, and
remove the FIXME's.
I have been going down into a bit of a rabbit hole trying to figure out
why the namespace is not getting set up properly on certain attributes.
At one stage, I thought the issue might have been around here where
attributes were being adjusted (it is not). I started adding spec
comments to understand what was happening, and by the time I realised it
wasn't in this place, I was already in too deep!
Add a whole bunch of spec comments, and leave one or two minor FIXME's
where the spec seems to have changed since this was originally
implemented.
These were DeprecatedFlyStrings, but had no reason to be. We were not
making use of the O(1) lookup, so instead of porting it over to a
FlyString, just make it a StringView.
Previously these were DeprecatedStrings that contained a null state.
After the null state was removed, the nullability of these members was
broken. This doesn't seem to cause any problems currently as the HTML
parser is not inserting attributes with their full qualified name, but
after we fix that problem, this bug surfaces.
This required dealing with a *lot* of fallout, but it's all basically
just switching from DeprecatedFlyString to either FlyString or
Optional<FlyString> in a hundred places to accommodate the change.
